Like the Prius and as its name suggests, the Toyota TS050 Hybrid is a hybrid. It can run purely on it battery or on its ICE power, or combined. Like the Prius is makes funky noises. Except in the TS050’s cases those noises are dramatically funky. Volume up, fools! Watch until the end!

I love this video although I think this is actually an earlier Toyota TS030.
Yes, it is.
This is the video in the article, but from inside the car (sounds like the exact same pit stop):

And this is an example of the TS050 pulling away from a pit stop (7:26 if it doesn’t jump straight to it):

My bad!
Sounds surprisingly similar to a turbine “cranking over” and lighting off. Which is to say, pretty cool.
